In this thesis, we seasonally monitored species presence and distribution of
macrophytes in Šobec pond and its tributary. The tributary was one of the sample
sites, and the other two were a man-made pool in front of the pond. The pond was
divided into four sampling sites. We also monitored physical and chemical
parameters of water and water depth. In the laboratory, we determined
concentrations of phosphates and nitrates. We also made a RCA (Ripariran Channel
and Environmental Inventory) inventory of a pond, a tributary, and a man-made
pond. Altogether, we found 22 different species of macrophytes. 10 species were
submerged, 11 were emergent and one species was both submerged and emergent.
The species composition changed throughout the seasons at individual sample sites.
A few species were present at the beginning of the season and then disappeared. The
species composition differed not only between individual seasons but also between
sample sites. We found that water depth among all parameters (oxygen
concentration, conductivity, concentration of nitrates and phosphates, pH) had the
greatest influence on the presence and abundance of macrophytes in Šobec pond.
